USB support has been (re-)added to SkyOS, including of course the USB stack, a UHCI driver, support for control, interrupt, and bulk transfers, a USB HUB driver, a USB HID Keyboard driver, a USB HID Mouse driver, a USB Mass storage driver for CBI devices, including USB Harddisks, card readers, etc. The USB stack has been written from scratch and a new release containing USB support is expected.
